Hertel 83246868 Chucking Reamer 1/32 in Solid Carbide

Product Description

The HERTEL 83246868 is a solid carbide chucking reamer designed for precision hole finishing in tight-tolerance applications. With a nominal diameter of 0.0312 inches (1/32 inch) and a diameter tolerance of 0.0000 to 0.0002 inches, this reamer delivers accurate, repeatable bore sizing in hard and abrasive materials where high-speed steel tooling falls short. The bright, uncoated finish suits a wide range of workpiece materials. Overall length is 1-1/2 inches with a 1/4 inch flute length. Four straight flutes and a right-hand cutting direction provide smooth, controlled stock removal. A straight cylindrical shank seats securely in standard drill chucks or collet holders.

This reamer is suited for precision machining operations in manufacturing, toolroom, and production environments. Its small diameter makes it appropriate for finishing micro-bores in watch components, instrument parts, medical device components, and other tight-tolerance assemblies. Licensed machinists, tool-and-die makers, and precision CNC operators are the typical end users. The solid carbide construction holds an edge longer than HSS in abrasive or high-hardness workpiece materials, reducing tool change frequency in production runs.

Key Features

• Solid carbide construction for extended tool life in hard and abrasive materials
• Diameter tolerance of 0.0000 to 0.0002 inches for precision bore finishing
• Four straight flutes with right-hand cut for smooth, controlled material removal
• Bright, uncoated finish compatible with a wide range of workpiece materials
• Straight cylindrical shank for use in standard drill chucks and collet holders
• Compact 1-1/2 inch overall length suits confined or short-reach bore applications

Compatibility

Designed as an OEM-style chucking reamer for use in standard drill chucks, collet chuck holders, and CNC machining center spindles accepting a straight cylindrical shank at 1/32 inch nominal diameter.

Installation Notes

Installation and use should be performed by qualified machinists or CNC operators familiar with reaming operations. Ensure the machine spindle and chuck are fully stopped and de-energized before loading or removing the reamer. Use appropriate cutting fluid for the workpiece material to manage heat and extend tool life. Do not use this reamer as a drill; always pre-drill the hole to the correct undersize before reaming.
